Big Crunch or Big Rip?

Again, it isn't that there are an equal number of bosons and fermions in general, just that there should be an equal number of TYPES of bosons and fermions, which pair up accordingly.

I use the term Graviton loosely to describe the threads of spacetime, you are right that they have not been experimentally confirmed, but a mesh of massless spin 2 particles fits perfectly with the model of spacetime I have in my head.

the model of spacetime I have in my head

If it's a good model then I would strongly suggest publishing it in the Physical Review.

Still working out the mathematical formulation, though I am attempting to contact a fellow Einsteinian I learned about recently who is working down the same path I am (regarding acausality and the structure of spacetime as a phenomenonological explanation for quantum effects), getting my letters typed up and ready to send out to him and Smolin actually.

It isn't easy to get published if you aren't affiliated with a college or have someone to endorse you.

Essentially though, if you know anything about loop quantum gravity, it is VERY similar to the description I hit upon, and I think somewhere between Smolin, Hadley, and myself we will find a completely unified theory of relativity which naturally produces quantum mechanics and the four forces in a local but acausal manner.

So how do they add up? In terms of mass, bosons and fermions are in two different leagues...

That's the crux of the matter, you are correct. But in a theory of quantized spacetime, it is the two distinct topologies of squares of energy that is equal in numbers.
Actually there are more photon bosons than baryonic or leptonic fermions in the entire universe.

[Max™]

Being Bosonic or Fermionic doesn't depend on mass.

Helium atoms are Bosons, for example.

[AntonioLao]

bosons and fermions are in two different leagues...

bosons push while fermions pull. Push and pull as what a force does.

[dipayankar]

They seem more like force particles...

bosons push while fermions pull. Push and pull as what a force does.

[AntonioLao]

That's right. Bosons are more pushy than pully fermions.

That particle zoo is growing again. Just when I thought I was getting down to the basic proton/electron/neutron, which is in a sense the results of that interplay, or dynamics, of those 3 quarks. Then suddenly there are the " force carriers " ( photons, gluons, graviton, W,Z ) I believe " the ghost particle " photon is the only one observed. And than bosons, fermions,leptons, mesons, neutrinos..........Too much classification........cannot compute.......
Positive, negative, neutral. Do we need more to desribe our universe. Trinity making the One Whole and Complete. To be whole to your soul is ecstasy.

Including antiparticles the count of elementary particles is set at 61. Reference: Martinus Veltman's Facts and Mysteries in Elementary particle Physics, Page 69, World Scientific Publishing, 2003. However, in a theory of quantized spacetime (TQS) as squares of energy, all elementary particles are composed of multi-dimensional H-pluses and H-minuses with given algebras for binary operations of addition and multiplication of charge and mass quantization.
